摘要 随着近年来交通安全事故的剧增和人们对于桥梁景观要求的提升,城市桥梁防撞护栏的安全性和美观性备受人们关注,因此有必要对城市桥梁防撞护栏的设计进行研究。根据规范并结合工程实例,对城市桥梁半刚性防撞护栏进行了抗倾覆验算,并采用有限元软件建立梁板实体模型,模拟汽车与防撞护栏的撞击。为城市桥梁防撞护栏的设计方法和一般设计流程提供了借鉴。 With the rapid increase of traffic accidents and the improvement of people’s requirements for the bridge landscape in recent years,the safety and aesthetics of the urban bridge anti-collision guardrail has attracted people’s attention,so it is necessary to study the design of the urban bridge anti-collision guardrail.In this paper,according to the code and the engineering example,the anti overturning checking calculation of semi-rigid anti-collision guardrail of urban bridge is carried out,and the solid model of beam and slab is established by using the finite element software to simulate the i MPact of automobile and anti-collision guardrail.It provides a reference for the design method and general design process of anti-collision guardrail of urban bridge.
